基于GPRS的风井综合参数安全监控

GPRS Based on Parameters of Ventilation Shaft Integrated Control System Software Design

采用GPRS无线网络传输数据,系统接口电路通过RS-485网络和80C552单片机的串行接口,构成多机通信网络。该上位机系统通过VB6.0中的通信控件MSCOMM实现了以PC主机与多台单片机分站的串行通信,并利用VB6.0编程进行实时数据的采集处理及控制、数据实时显示、报表打印和报警等功能。

The design of the main elements of the ground for ventilation shaft comprehensive monitoring software design parameters. GPRS wireless network used to transmit data, system interface circuit through the RS-485 networks and 80 C552 mcu serial interface, a multi-machine communications network. The host computer system through the communication control VB6.0 MSCOM achieve a PC host with multiple sub-station serial communications, and use real-time programming VB6.0 data acquisition and processing and control, real-time data, print statements and alarm functions.
